Application September 13, 1938; Serial No. 229,767 I.

1 Claim. (01. 272-33) these beingfitted toa winged collar l4 and also The invention relates to swings and more particularly to'rotary swings.

The primary object of the invention is the provision of a swing of this character, wherein a series of seats are suspended from a rotator so that the swing can be occupiedqby a plurality of persons and when seated it is possible through mechanical "means manually operated for the rotation of the swing thereby'giving amusement x lo and afiording pleasure to participants in the use of the swing.

Another object of the invention is the provision of a, swing of this character, wherein each or anumber of occupants can actuate the same for the driving of said swing, beingrotatable and the driving through manual control being effected with minimum labor or eifort on the part of an operator. v v

A further object of the invention is the provi- 1 '20 sion of a swing of this character, which is com- 30 the preferred embodiment of the invention and pointed out in the claim hereunto appended.

In the accompanying drawings:

Figure 1 is an elevation of a swing constructe in accordance with the invention.

Figure 2 is a fragmentary vertical sectional view thereof.

Figure 3 is a sectionalview taken on the line 3-3 of Figure 1 looking in the direction of the arrows. I l a Figure 4 is a sectional view taken on the line 44 of Figure 1 looking in the direction of the arrows.

Figure'5 is an elevation partly broken away of certain adjuncts of the swing.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings in detail, the swing with a base H suitably anchored or at rest upon a foundation. Turnable on this upright Ill close.

to theupper end thereof is a horizontally arranged cross head in the form of abar 12, being a 55 strengthened or reinforced by brace rods l3,

With'these and other objects m'vsmhe m- Depending from the under side of the bar l2 and at opposite sides of the upright 10 are bearv shafts l6e1fect the rotation of the bar [2 in a single direction and thus rotation of the swing is had. The hangers I]. are fixed to theshafts 16 next thereto while the hangers H are loose upon the shafts I6 next thereto.: On theinnermost hanger of the pair l'l there is fixed a pivot bracket 24 for pivotal support of a lever 25 which has pivotal connection at 26 with apair of spaced links 21', these being pivoted at 28 to bearings 29 on the platform I9. The pivotal connection 26 constitutes a foot treadle operated by the foot or feet of an occupant of the seat suspended by the hangers l'l'.

Connected with and active upon one of the Q links 21 is a coiled spring 30 which is also connected with the platform l9 and this spring is a retractile spring. The lever 25 has slidably connected therewith a cross head sleeve 3| pivotally mounted in spaced crankarms 32 fixed to the shafts l6 next thereto. I

Arranged inwardly with respect to the inner-' most hanger ll of the other pair is a lever 33,

being journaled in a bearing 34 beneath the platform 19 next thereto. Thislever 33 ispivotally connected to a link 35 which is pivoted to a crank arm 36 on a pedal operated shaft 31 having the foot pedals 38.

The lever 33 slidably fits in a cross head sleeve '39 pivoted to a pair of spaced crank arms 40 suspended from the bar [2, being fixed thereto and having clearances 4| for the shafts it next thereto.

An occupant of one of the seats l8 can manually manipulate through treadle action the treadle 26 and in this manner the swing will be caused to rotate in one direction. Now another occupant in the other seat l8 can operate the pedals 38 manually causing the shaft 31. to be rocked and thus through such pedal action there will be veffected the rotation of the swing. Additionally, the seats l8 can be oscillated concurrently with the rotation of the swing and driving power furnished by occupants of either of the seats 18 or both.

What is claimed is:

A rotary'swing comprising a fixed vertically disposed stationary shaft, a horizontally arranged bar forming a cross head having a central sleeve-like hub rotatably fitting the upper end of said shaft, bearings depending from the underside of said bar beyond opposite sides of the shaft, rocking shafts journaled in said bearings and extending laterally from opposite sides of the shaft, a ratchet gear fixed to the first mentioned shaft, cranks fixed to said 'second named shafts, ratchet dogs pivoted to said cranks and reversly operative .with the said ratchet gear,

' swinging levers.

a pair of hangers fixed to one of the last mentioned shafts, a pair of hangers loosely fitted with the other of the said pair of last mentioned shafts, seats carried by said hangers, levers swingable relative to said seats, means associated with the seats for imparting swinging movement to said levers and manually controlled,

pairs of crank arms, one pair being fixed to one of the pair of last mentioned shafts, the other pair of crank arms being in loose embracing engagement with the other of said pair of last mentioned shafts and suspended from the cross head bar, and cross head sleeves pivoted to the pairs of crank arms and slidably fitted with the JERRY BREWSTER, SENIOR.
